http://bugzilla.opensuse.org/show_bug.cgi?id=1057539 Bug ID: 1057539 Summary: VUL-0: CVE-2017-14171: ffmpeg: DoS in nsv_parse_NSVf_header() due to lack of an EOF check Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Security Assignee: jengelh@inai.de Reporter: abergmann@suse.com QA Contact: qa-bugs@suse.de Found By: Security Response Team Blocker: --- CVE-2017-14171 In libavformat/nsvdec.c in FFmpeg 3.3.3, a DoS in nsv_parse_NSVf_header() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted NSV file, which claims a large "table_entries_used" field in the header but does not contain sufficient backing data, is provided, the loop over 'table_entries_used' would consume huge CPU resources, since there is no EOF check inside the loop.
